Abstract

Alkyl aromatic hydrocarbons having 7-15 carbon atoms are subjected to intra- or inter-molecular rearrangement of the alkyl groups at 200-600 DEG C. in the presence of hydrogen mordenite. Reaction is effected at 7-140 atm. and 0.1-25 w./w./hr. with 1-50 mols. of hydrogen per mol. of hydrocarbon. The catalyst may optionally contain by base exchange or impregnation a metal of Group 1B, 6B or an iron-group metal in an amount of 0.01-20% wt. The isomerization of xylenes and disproportion of toluene and ethyl-benzene are exemplified.
